[Luther Chan]

Hi guys,

Will somebody out there let me know which are the best BBS software.
Please send me infomation on the features and how to get it.

My basic requirement it able connect by two modem users and a console operator.
Search function such as subject, and name search are basic requirement.
The software may run in either DOS or UNIX.

Thank you in advance.
